Solution

1. Preparation

Gather tools and materials: OBD-II scanner, compression tester, socket set, oil catch pan, fresh oil, and a new oil filter.
Ensure the vehicle is parked on a level surface, and the engine is cool.
Disconnect the battery to ensure safety during the repair.

2. Address Oil Leaks

Sub-steps:
- Raise the vehicle using jack stands and remove the undercarriage cover if applicable.
- Inspect gaskets and seals (valve cover, oil pan, etc.) for leaks.
- Replace any damaged gaskets or seals using appropriate torque specifications.
Tools Required: Torque wrench, socket set.

3. Replace Engine Oil and Filter

Sub-steps:
- Drain the old engine oil using an oil catch pan by removing the drain plug.
- Replace the oil filter using an oil filter wrench.
- Reinstall the drain plug and torque it to the manufacturer's specifications.
- Refill the engine with the recommended type and amount of fresh oil.
Tools Required: Oil catch pan, wrench set, oil filter wrench.

4. Repair or Replace PCV System

Sub-steps:
- Locate the PCV valve and remove it for inspection.
- Clean or replace the PCV valve if clogged or faulty.
- Inspect and replace any damaged hoses connected to the PCV system.
Tools Required: Pliers, screwdriver.

5. Perform Compression Test

Sub-steps:
- Remove spark plugs to gain access to the cylinders.
- Connect the compression tester to each cylinder and crank the engine to check compression values.
- Compare results to manufacturer specifications; replace or repair components if compression is low.
Tools Required: Compression tester.
